method of constructing such subdividers,

and consists of a subdividerin which an an- 5 unlar perforated plate has the blades which 1 extend from the innerto the outer periphery of the annulus secured to such plate by means of lugs formed uponone edge of each i blade and integral therewith, which lugs are passed through openings in the plate iandrare turned over and clenched upon the:

side. of the plate 'oppositeto that from Which the blade projectsy-and in the method of] constructing such subdividers by forming openings for llquid 1n the annular plates,

arranged from theinnerto theouter pen rlphery of the annulus 111 lines correspond mg to the desired line of the respective blades,forming integral lugs upon one edge of each blade, and securing them. to the plate by passing the lugs'throughgthe openings therein and bending the ends ofthe lugs over and clenching them upon the side of the plate opposite tothat from whichthe blade projects; preferably also in forming' flanges at right anglesto the planeof the blades and producing the lugs by cutting them from such flanges at lIllQlVfllS along their length, thereby leaving openings in*the1 flanges which correspondito openings in the late.

The mate rial cut .fronrt-heflanges :to form the lugs .leaveopenings .in the, flanges which are locatecl soas to correspond or register with openings o .in the plate,'when theblades are attached thereto. These lugs are advantageously cut andibent at right angles to? the things in such manner that when the blades are to be attached in pairs, one upon each side of the plate and both in the sameplane, a lugiofaeblade upon one side of the plate will pass through a hole at one limit thereof, and a lug-of, the blade on the opposite side of the plate will pass through the'same hole at the opposite limit thereof and the respective lugs will be bent over in opposite directions, as illustrated inFig. 7; and when thus constructed and arranged it will be found advantageous to have aportion vof the lugs on each blade bent :over in one direction and aportion in the other direction, asshown 'MOdlfiCtlfilOIlS of the manner of forming thelu-gs-of .therespective blades and clenching themlupon the plate are illustrated in 1 FigsfS to .11, wherein in Fig.8, the long clenching lugs are all upon 'one blade, and the lugs "Z3 upon the opposite blade. are made onlyas long as the thickness of the plate and v simplyf look, upon the edge of the "plate in the opening, but do not extendthrough and clench over upon the opposite side of the plate; in Fig. 9, the lugs are in pairs, ashort one i simply interlocks with the plate, and

the other a long one, Z passes through the plate and clenches upon the opposite side. in these modifications the short lugs serve to prevent any longitudinal movement of the blade along the surface of the plate, while the long lugs serve to secure the blades to the plate. in rigs.,l0 and 11 are illustrated the manner of attaching the blades B to the plate A by means of lugs l projecting directly from one edge of the blade instead of from flanges, as in the other figures. As shown in rig. 10, the liquid openings 0 in the plate A are formed with narrow elongations 2) in each direction, and a lug Z upon a blade on the opposite sides of the plate A, projects through one of these narrow elongations and each is bent over upon the plate in a direction opposite to that of the other, as illustrated. In Fig. 11 the blades upon opposite sides of the plate and with such lugs projecting from one of their edges, are shown in proper position for insertion through the narrow openings in the plate.

One advantage of having flanges upon the blades and cutting the lugs therefrom, is that the long lugs of each blade extend through the openings in the plate and in the flange of the opposite blade, and are clenched over and upon the flange of the opposite blade, thus serving as a means for securing both blades to the perforated plate by the 'lugs of either blade, and this is the preferable form. For the purpose of strengthening the ends of the blades at the outer periphery of the annular plate, that end is bent around a piece of stilf wire, and where the blades are secured to the plate in pairs, one upon each side of the plate and in the same plane, this stifiening wire extends across the width of the two blades, being made continuous from one to the other, and thus assists in holding the ends of the blades firmly upon the plate, particularly when the wire is soldered to the blades, as occurs in practice when each subdivider is dipped into melted tin after all the blades have been secured to the plate.

The flanged blades may be attached to the annular plates by other means than the integral lugs, for example, by rivets, but I have found the method of attachment by the integral lugs as hereinabove described to possess practical utilities superior to any other.
